摘　　要：高校突发事件学生心理危机预警指标体系主要来自于专家经验,主观性强、冗余度大,且通过该指标体系搜集到的信息系统是一个不完备的偏序系统。文章提出了一种基于限制优势关系粗糙集的指标约简方法,将限制优势关系引入目标信息系统的部分一致协调约简,构建限制优势关系下的部分一致函数和部分一致辨识矩阵,实现预警指标的约简,获取学生心理危机的引致要素;最后,结合算例进一步说明该方法的有效性。The common early warning index system of university student psychological crisis which is constructed based on the expert experience has strong subiectivity and big redundancy. The informa- tion system based on such index system is an incomplete ordered system. For this problem, a method of index reduction based on limited dominance relation rough sets is proposed. By introducing the lim- ited dominance relation into partial consistency reduction of the target information system, the partial consistency function and partial consistency discernable matrix are built to reduce the early warning in- dexes and to obtain the key indexes which lead to student psychological crisis. An example demon- strates the validity of this method.
